Export functionality experiencing 504 Gateway Timeout error

[kokodak]

What happened:
The export functionality for documents, which should allow exporting in PDF, HTML, and Markdown formats, is currently not working. When the export API is called, there is no response from the server, resulting in a 504 Gateway Timeout error.

What you expected to happen:
The documents should be exported successfully in the selected format without encountering a timeout error.

How to reproduce it (as minimally and precisely as possible):

1. Create or select a document.
2. Attempt to export the document using the export API.
3. Observe the occurrence of the 504 Gateway Timeout error.

Anything else we need to know?:
This issue seems to have surfaced recently, as the export functionality was previously working without issues.
